These two-bolt seat posts have a generous 30mm of offset, among the longest ever. This is very important for those who ride leather saddles that often have little fore-and-aft adjustment due to the short rails.
The VO seatpost is internally ovalized to keep the weight down. The adjustment is from the bottom and the two-bolt design makes it easy to precisely adjust the seat angle. Also note that the head is integral with the post, not pressed on as on many modern posts. This makes them stronger and lighter.
